Figure 1

Box-and-whisker plots of amplification efficiency and coefficient of determination (R²) obtained from short and long amplicons both in frozen and FFPE tissues.

(a): Box-and-whisker plot of amplification efficiency. (b): Box-and-whisker plot of coefficient of determination (R²). Frozen-short A: quantification with short-A amplicons in frozen tissues. Frozen-long: quantification with long amplicons in frozen tissues. FFPE-short A: quantification with short-A amplicons in FFPE tissues. FFPE-long: quantification with long amplicons in FFPE tissues.
